2006 Saturn Ion Fuel Pump Access: A Step-by-Step Owner’s Guide

If you own a 2006 Saturn Ion and need to access the fuel pump, here is the bottom line: the fuel pump module sits inside the fuel tank, and on this model, you must remove the entire fuel tank from under the vehicle—there is no access panel under the rear seat like some other GM cars. This means the job takes 2 to 4 hours for a DIYer with moderate experience, requires a jack and jack stands, and demands careful handling of fuel system components to avoid safety risks . Below, we break down exactly how to access the pump, what tools you need, what to watch for, and how to avoid common mistakes.

Why Accessing the Fuel Pump on a 2006 Saturn Ion Requires Extra Work

The fuel pump module on the 2006 Saturn Ion is mounted inside the fuel tank, which is located at the rear of the vehicle and held in place by two metal straps attached to the underbody . Unlike the Chevrolet Cobalt or Pontiac G5, where the pump can often be reached through a service panel under the rear seat, the Saturn Ion does not offer that convenience . The service manual for the 2006 Ion clearly states that the first step in fuel pump module replacement is to remove the fuel tank .

This is not a job you can shortcut. The tank is made of high-density polyethylene, and the pump module includes the fuel level sensor, the fuel tank pressure sensor, the pump itself, and the fuel pressure regulator all in one assembly . You need to lower the tank safely, disconnect the electrical and fuel line connections, and then unthread the lock ring that holds the module in place.

Tools and Parts You Will Need

Before you start, gather everything in one place. Missing a single tool can turn a two-hour job into an all-day ordeal. Here is the complete list:

  1. Socket set (metric, since this is a Saturn) – for tank straps, bolts, and brackets
  2. Wrenches – for fuel line fittings that may be corroded
  3. Flathead and Phillips screwdrivers – for smaller fasteners and prying
  4. Jack and jack stands – non-negotiable for safely raising the vehicle
  5. Fuel line disconnect tool – for the quick-connect fittings
  6. Fuel tank lock ring remover – the proper service tools are SA9156E and J 45722 (or the equivalent J 39765)
  7. New fuel pump module – make sure it is compatible with your Ion’s engine size (2.2L, 2.0L, or 2.4L) and emissions system
  8. New fuel sender seal/gasket – do not reuse the old one
  9. Safety gear – gloves and eye protection
  10. Approved fuel container – for draining the reservoir bowl inside the module

Using the correct lock ring tool is critical. The factory service manual warns against using a hammer and screwdriver or impact tools to remove the lock ring, because you can damage the ring or the tank . The lock ring can take significant force to release, so a long breaker bar on the proper wrench is the right approach.

Step-by-Step: How to Access the Fuel Pump

Here is the full sequence, based on the factory service procedure and practical DIY experience:

Step 1: Relieve Fuel System Pressure and Disconnect the Battery

The very first thing you must do is reduce the risk of fire. Disconnect the negative battery cable. Then remove the fuel pump fuse and run the engine until it stalls, or use the proper pressure relief procedure outlined in your owner’s manual . Work in a well-ventilated area and keep any ignition sources far away.

Step 2: Raise the Vehicle and Drain the Tank

Safely raise the rear of the vehicle using a jack and support it with jack stands. You want the tank as empty as possible before lowering it. A full tank is extremely heavy and dangerous to handle. If you have less than a quarter tank, you can usually proceed, but draining it completely is safer.

Step 3: Remove the Fuel Tank

This is the most labor-intensive part. You need to:

  • Disconnect the fuel tank harness electrical connector from the fuel pump module
  • Remove the fuel tank harness from its retaining features on the tank
  • Disconnect the fuel feed and return lines from their retaining clips
  • Support the tank with a floor jack (use a piece of plywood to spread the load)
  • Unbolt the two metal straps that hold the tank to the underbody
  • Carefully lower the tank just enough to access the top of the module

Step 4: Remove the Fuel Pump Module

Once the tank is lowered and you can reach the top of the module, follow this sequence:

  1. Disconnect the electrical connector from the fuel pump module
  2. Unthread the lock ring using the J 45722 wrench and a long breaker bar, turning it counter-clockwise . If the lock ring is stamped “DO NOT REUSE,” or if it is warped, replace it
  3. Slowly lift the module until the fuel level sensor float arm is just visible
  4. Tilt the module toward the front of the tank so the float arm clears the opening without bending
  5. Remove the module and immediately pour the fuel from the reservoir bowl into an approved container
  6. Discard the old seal – do not reuse it under any circumstances

Step 5: Install the New Module

Installation is the reverse of removal, but there are important details:

  1. Position a new seal onto the fuel tank opening
  2. Slide the new lock ring over the feed and return lines of the new module
  3. Tilt the module toward the front and lower it into the tank, making sure the fuel lines align with the cutouts
  4. Hand-thread the lock ring until it is fully seated in the retaining tabs, then tighten it clockwise with the wrench
  5. Reconnect the harness and fuel lines, then reinstall the tank

Step 6: Reassemble, Refill, and Test

Bolt the tank straps back in place, reconnect everything, refill the tank, and turn the key to the ON position (without cranking) a few times to prime the fuel system. Then start the engine and check for leaks around the module and the fuel lines .

Common Mistakes and How to Avoid Them

Even experienced DIYers make errors on this job. Watch out for these:

  1. Bending the float arm – This is the most common damage. Always tilt the module when inserting or removing it
  2. Reusing the old seal or a warped lock ring – The seal must be replaced every time. The lock ring should be checked for flatness; if warpage exceeds 0.41 mm (0.016 in), replace it
  3. Using impact tools on the lock ring – This can crack the plastic tank or damage the ring
  4. Forgetting to check the RPO code – The 2006 Ion with the 2.2L engine has different fuel pump part numbers depending on the emissions system (NT7, NU1, or NUA). Check the RPO sticker in the trunk or glovebox before ordering
  5. Skipping the special coverage check – General Motors issued recall 12190 for cracked fuel pump modules on 2006–2007 Saturn Ions, along with Special Coverage Bulletin 12191B that extends coverage even beyond warranty. If you have a fuel leak or smell gas, check with a GM dealer first—you might get the pump replaced for free

Cost Considerations

If you decide to have a professional do the job, expect to pay between $260 and $650 for parts and labor, depending on whether you choose aftermarket or OE parts and what local labor rates look like . A bare aftermarket fuel pump module runs $60 to $200, while an OE or brand-name module costs $180 to $350 . Labor typically adds $100 to $300 because the tank must be dropped . Some estimates from repair shops run higher, up to $1,046 to $1,148, largely due to parts pricing and the time involved .

The DIY route saves you the labor cost, but only if you are comfortable working with fuel systems and have the right tools. The job is rated as intermediate to advanced . If you are not confident, pay the professional—it is cheaper than a fire or a damaged tank.
